三维收扩喷管流场计算代码，源自美国PDAS开源代码项目。-This program is a "work in progress" and is not ready for general release.
I have included it on the disc so those who have a special interest may see
the original code plus my modifications to date.

The AS5030 is a contactless magnetic rotary encoder for
accurate angular measurement over a full turn of 360°.
It is a system-on-chip, combining integrated Hall elements,
analog front end and digital signal processing in a single
device.
